“…Using the example of LAPSSET, I demonstrate how imaginaries and material practices of development corridors could be understood as playing a particular socio-political function in three interrelated ways: as (1) practices of establishing new frontiers of extractive capital accumulation that (2) create fragmented state territoriality characterised by complex interaction between the state and private actors, and (3) advance capitalist "modernity" that marginalises populations of the regions "opened up" by infrastructural developments. Besides providing theorisation for the emerging geographical research on development corridors (Enns, 2017;Lesutis, 2019a;Mosley & Watson, 2016), these three ways of reading the socio-political function of LAPSSET in Kenya also contribute to the recent geographical scholarship on mega-infrastructures that particularly focuses on the planetary restructuring of global capitalist relations through urban infrastructures (Easterling, 2014;Kanai & Schindler, 2018;Rao, 2014;Wiig & Silver, 2019). The paper shows how the globally structured politics of infrastructuresuch as development corridorsadvance capitalist expansion by materialising not just in urban or peri-urban contexts, as is common to focus within the literature, but also more broadly re-produce geographies of states, characterised by extractivism, contested territorialities, and normative ordering of life.…”
